Sliding Mode Control for Synchronous Electric Drives

This volume presents the theory of control systems with sliding mode applied to electrical motors and power converters. It demonstrates the methodology of control design and the original algorithms of control and observation. Practically all semiconductor devices are used in power converters, that feed electrical motors, as power switches. A switching mode offers myriad attractive, inherent properties from a control viewpoint, especially a sliding mode. Sliding mode control supplies high dynamics to systems, invariability of systems to changes of their parameters and of exterior loads in combination with simplicity of design. Unlike linear control, switching sliding mode control does not replace the control system, but uses the natural properties of the control plant system effectively to ensure high control quality.

This is the first text that thoroughly describes the application of the highly theoretical control design approach to synchronous drives in practice. It examines in detail the different features of various types of synchronous motors and converters with regard to sliding mode control design. It further presents a detailed analysis of control issues and mechanical coordinate observation design for various types of synchronous motors, of power converters, and various drive control structures. It also discusses the digital implementation of control, observation and identification algorithms. The potential of sliding mode control and observation are moreover demonstrated in numerical and experimental results from real control plants.

This work is intended for professionals and advanced students who work in the field of electric drive control. It is also recommended to experts in control theory application, who work with sliding modes for the control of electrical motors and power converters.

Sergey Ryvkin first graduated with high honors as an engineer from the Moscow Institute for Aviation Engineering (Technical University), after which he gained his PhD degree from the Institute of Control Sciences (USSR Academy of Science) in Moscow and was awarded a DSc from the Supreme Certifying Commission of Russian Ministry of Education and Science in Moscow. He is currently a professor at the Russian State University for Humanities and a leading researcher at the Laboratory of Adaptive Control Systems for Dynamic objects at the Trapeznikov Institute of Control Sciences from the Russian Academy of Sciences. His lines of research are the application of the sliding mode techniques to control of electrical drives and power systems and to their parameter observation. Prof. Ryvkin holds several patents and published one monograph, five textbooks and more than 100 papers in international journals and proceedings. He is a member of the Russian Academy of Electrotechnical Sciences and a senior member of the IEEE. Eduardo Palomar Lever got his BSc degree in electromechanical engineering from the National Autonomous University of Mexico, after which he obtained an MSc degree in control engineering and computing sciences from the University of Warwick, UK, and a PhD on sliding regimes to control servomechanisms from the University of Sussex, UK. He is a full time research professor at the University of Guadalajara. His lines of research focus on nonlinear control systems and servomechanisms control using digital sliding modes. Prof. Palomar-Lever’s teaching specialties are advanced-level control engineering, automation, advanced mathematics, computing languages, software development, and statistics. He earlier published a book on ferroelectric materials as well as several papers on sliding motion control and biomedicine in international journals and conference proceedings.
